'HETlNG-'STOVE SPECIFICATION formng part of Letters Patent No. 462,186, dated October 27, 1891.

T0 all whom it may con/cera:

Be it known that I, GEORGE BWOODARD, a citizen of the United States, residing at Olean, in vthe county of Cattaraugus and State of New York, have invented new and useful Improvements in Heating-Stoves, of which the following is a specification.

This invention has for its object to provide a novel, simple, economica'l, and efficient stove for heating apartments by means of hydrocarbon fluids in such manner that the flame from a burner heats to a high temperature a metallic hood, upon which air is delivered and heated to fiow into the apartment, while portions of the heated air are dircoted into the hood to support combustion.

The invention also has for its object to provide a novel const-ruction of burner, whcreby the oil-drippings fiow from a burner-tip into a surrounding Chamber or rcceptacle for the purpose of providing a snbsidiary flame'.

To accomplish these objects my invention consists in the features of construction and the combination or arrangement of devices hereinafter described and claimed, reference being madeto the accompanying drawings, in which- Fi gure 1 is a Vertical sectional view, partl y in side clcvation, of my improved heatingstove; and Fig. 2 is a detail view showing a modified construction of bu rner.

In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, referring to the d rawin gs, whereiu- The numcral 1 indicates the metallicburner-body, having at its base portion a laterally-projecting fiange 2, provided with a rim 3 for the purpose of sustaining and retaining in proper position a cylindrical shcll or casing et, which rcsts upon the flange and is confined thereupon by the rim.

The burner-body is preferably provided with attached legs or feet 5 for the purpose of supporting it in a slightly-clevated position, and at the center of the burner-body is formed a Vertical passage-Way (3, terminating at its top portion in a jet-oritice 7 of reduccd diameter. The burner-body is formed at the center with the upwardlyprojecting cupshaped burner 8, containing a ooncavity in its upper side and surrounded by an annular Application filed May 4, 1891. Serial No. 391,574. (No model.)

receptacle or chamber 9 for providing a subsidiary flame, as will hereinafter appear. The lower extremity of the passage-Way 6 communicates with an oil-supply pipe 10, having a regulating-Valve 12 and adapted to connect with an elevated reservoir con'taining the oil or hydrocarbon fluid, so that the latter is supplied to the burner under pressure.

The Vertical annular portion 13 of the burner-body, which constitutes the outer Wall of the receptacle or chamber 9, serves to support a hood 14, which is expanded near the middle of its length, as at 15, and tapers toward each extremity, so that the hood is of double conical form. The lower conical portion is provided at its base with a series of pendent feet 1G, adaptcd to rest upon the upper edge of the Vertical wall 13, and having at their inner sides the depending fingers or arms 17, which engage the inside of the Vertical wall, and thereby retain the hood in a perpendicular position upon the burnerbody. The pendent feet 16 serve to elevate the lower edge of the hood from the upper edge of the burner-body, and inasmuch as these feet are separated from each other a series of lateral spaces orpassages 18 are provided in proximity to the burner for the pas- Sage of air from the interior of the shell or casing 4 to the fiame of the burner for supporting combustion.

The shell or casing is provided at one side with an orilice 19, closed by a suitable door 20 for the purpo'se of ntroducing a torch or other device to light the burner, and the opposite side of the shell or casng is provided with a cold-air flue 21, adapt-ed to communicat-e in any suitable manner with the external atmosphere for the purpose of conducting air into the shell or casing and delivering duet portions of the heated air to the flame for the purpose of supporting combustion. By heating the air prior to its entrance to the burner the generation of smoke is in a large measure reduced. The upper contracted extremity of the hood is connected Witha flue IOO or smoke-pipe 23 for the purpose of carrying' ofi the products of combustiou.

The regulating-valve in the oil-supply pipe eontrols the supply of oil to the burner, and in operation the oil Will accumulate in the concavity formed in the upper end of the burner .and overflow into the surrounding' receptacle or chamber 9. The accumulating` oil in this receptacle or chamber becomes ignited, and thereby provides a subsdiary fiame, which materially increases the heating capacity of the stove and renders thel apparatus more useful, desiralole, and efficient in practical operation.

The burner-body and the hood are preferably composed of cast-iron as being the material most suitable' for the conditions required=,-in that the metal can be quickly heated generates consid'erable heat for heating the infiowi'ng. cool air, which is thus utilized in heati'ng the apartment wherein the stove is arranged'.

The construction of the double conical hood is s-uch that i't can be quickly and convenien'tly removed and replaced for the purpose of re'adily cl'eanfiing the burner or givin'g it such other attention as occasionV may demand.

In Fig'. 2 I have exhibited the orifice 7 in the burner as provided With atube 24, having a sphe'rical perforated head 25, and, if desired, this modified construction of burner may be used.

The sh'el'l o-r casi'ng may be com-posed of sheet metal or any other material that Will fulfill the-conditions required; but sheet metal is preferable, in that it is rapid-ly heated and can be practieally used, since it is not exposed tol theI direct action of the fiame from the b'urner'.

Having thus described my invention, what I claiim is- 1. The combination, in an oil-stove, of a oast-iron burner-body formed integral with an oil passage-way, and a burner having` a concavi-ty in its upper side and surrounded by a receptacle or chamber into which oil from the concavity of the burner overflows for providing a subsidiary fiame, a hood having lateral air-inlet spaces or passages in proximity to the burner and provided With feet detachably engaging the upper end portion of the burner-body, and a shell or casing surrounding the burner-body and hood, having hot-airdischarge orifices at its top portion and provided` with a cold-air flue adapted to communicate with the external atmosphere for delivering air upon the heated hood, substantially as described.

2. The combination, in an oil-stove, of a bu rner-body having a central oil-burner, a metallic hood detachably engaged with the upper end portion of the' b'urner-body and provided with lateral air-inlet spaces or'passages for the inflow of heated air to support combustion, and a shell or casing surrounding the burner-body and. hood, having ho-t-air-delivery orifices and provided with a flue for communieating' with the externalatmosphere to .deliver such air upon the heated hood for its passage to the burne-r and to' an apartment, substantially as described.

3. The combination, in an oil'stove, of a burn'er-body having a lateral flange at its base and provided at its upper portion with an oil-burner, a double conical hood detach'- ably eng'aged With the upper portio'n of the burner and provided with lateral. air s'paces or passages for the infio'w of heated air to support combustion, and a shell or casing surrounding the burner-body and hood, having hot-air-discharge orifices at its' 'top portion and provided With a cold-air fi'ue adapted to communicate with the external atmosphere for delivering such air upon the heated hood, substantially as described,

In testimony Whereof I have hereunto set my hand and aftixed my seal in preseuce of two subscribing witnesses.
